Show HN: I built an email agent for founders who are stuck in email

Dirac, an AI email agent for founders, connects to Gmail or Outlook, learns the user's writing voice from sent mail, and delivers a morning brief with summaries, priorities, and ready-to-send drafts before the user opens their laptop. The tool aims to save founders from losing their first hour to email triage, offering a $20/month subscription as a cheaper alternative to a full-time assistant.
